PCB Assembly Components - Frequently Asked Questions
What are the minimum component spacing requirements for reliable assembly?
Component spacing requirements vary by assembly method and component type. Surface mount components typically require 0.25mm minimum spacing for Class 1/2 designs, whilst high-density assemblies may use 0.15mm clearances. Proper spacing prevents solder bridging, allows for rework access, and accommodates manufacturing tolerances. Hex spacers ensure consistent board-to-board distances, whilst plastic screws provide secure fastening without stress-cracking in confined spaces.
How can I prevent thermal issues and component overheating during assembly?
Thermal management requires strategic component placement to avoid hotspots, adequate spacing for airflow, and proper heat dissipation paths. High-power components should be positioned with sufficient clearance, and heat-sensitive parts placed away from heat sources. Effective cable management using snap rivets and organised routing with heat shrink tubing helps maintain airflow whilst protecting connections from thermal stress.
What's the best way to manage cables and wiring in PCB assemblies?
Professional cable management prevents signal interference, mechanical damage, and assembly complications. Snap rivets provide quick, tool-free cable securing to panels and enclosures, whilst heat shrink tubing offers strain relief and environmental protection for wire splices. Proper cable routing maintains required clearances from sensitive circuits and allows adequate access for testing and maintenance.
Why do plastic enclosures crack around screw fasteners?
Standard machine screws can cause stress concentration and cracking in plastic materials due to their cutting action. Thread-forming screws specifically designed for plastics displace rather than cut material, creating secure fastenings without generating stress points that lead to failure. Proper pilot hole sizing and screw selection prevents costly enclosure damage during assembly and field service.
How do I calculate correct standoff lengths for multi-board assemblies?
Standoff length calculations must account for PCB thickness, component heights, required clearances, and thermal expansion. Measure the total stack-up including all boards and components, then add 1-2mm for manufacturing tolerances and thermal growth. Hex spacers in various lengths provide precise spacing control, whilst their male/female or female/female configurations allow flexible assembly architectures for complex multi-level designs.
